根据烷基叔胺萃取处理氰化浸金贫液的新工艺，设计一套日处理５００Ｌ贫液的半工业规模的系统。在山东莱州黄金冶炼厂连续进行了１２０ｈ的试验，试验验证了工艺研究中所提出的各项工艺参数，各项指标均达到要求，萃取设备运行正常。本试验为工业设计提供了依据。
According to the new technology of alkyl tertiary amine extraction and treatment of cyanide leaching solution, a semi-industrial scale system of 500L lean solution was designed. In Shandong Laizhou gold smelter for 120h continuous test, the test verified the process of the proposed process parameters, the indicators have reached the requirements, extraction equipment is operating normally. This test provides the basis for industrial design.
